A O2 UK pay as you go SIM that we activate before posting, with EU roaming switched on – so it works the moment you land, in the UK or in Europe.
O2 is one of the UK’s largest networks; giffgaff, Tesco Mobile and Virgin Mobile also run on it.

How it works
- Choose your option and pay with PayPal or card.
- We post your O2 SIM card by Royal Mail.
- Put the SIM in an unlocked phone and follow the activation steps in the pack.
The SIM is a 3-in-1 card (standard, micro and nano), so it fits any phone.
Delivery and postage
SIM cards are posted by Royal Mail, usually within one working day. Postage is worked out at checkout from the weight of your order: in the UK from £2.95 (Second Class Signed), £3.90 (First Class Signed) or £9.95 (Special Delivery next day); to Europe from £9.95; to the rest of the world from £15.95. Bigger packs weigh more, so postage for 25, 50 or 100 SIMs is higher. We post worldwide.
Keeping your O2 number
O2 usually expects the SIM to be used or topped up within about 6 months. Once you have the SIM you can top it up any time with our O2 top up vouchers, sent by email in minutes – handy if you live abroad and want to keep your UK number.
Questions
Why buy an activated SIM?
Some UK SIMs must be activated in the UK before they work. We do that for you, so the SIM is ready wherever it is delivered.
Does roaming cost extra?
Roaming charges and allowances follow O2’s current terms. Check them before heavy use abroad.
Can you post it to me abroad?
Yes – we post worldwide by Royal Mail, tracked options available at checkout.
